Ontario IESO Contracts for Large Scale Battery Storage

From Solar Thermal Magazine:

​S​unEdison, Inc., ​recently ​announced that it signed ​an agreement to supply battery storage to the province ​of Ontario​.​ ​This is to insure everyone in the province gets the electricity they need​ as it’s needed​, ​and to smooth the power flow from wind and solar​. This will eventually result in major improvement​s​ ​in how its grid functions​:

“By integrating energy storage into their grid, the Ontario IESO gains access to a powerful new tool that has the potential to transform how it operates the power system,” said Tim Derrick, SunEdison’s general manager of Advanced Solutions. “Batteries can be used to reduce grid congestion, smooth out power flow from solar and wind sources, and may help the IESO defer or avoid expensive upgrades to the grid.”
